Varnish is a web accelerator platform, which caches information for faster access. It’s occasionally called an HTTP reverse proxy too and it interacts between a web server and a browser. When a visitor opens a certain page, its content is requested by the Internet browser, and then the web server handles this request and returns the requested information. If Varnish is activated for a specific website, it will cache its pages on the very first visit and in case the visitor opens a cached page once again, the content will be delivered by the caching platform and not by the web server. The improved speed is an end result of the substantially faster response time that the Varnish platform offers as compared with any web server software. At the same time, this does not mean that the site visitors will continue being served the exact same content again and again, because any update on any of the pages is reflected in the content that the Varnish platform keeps in its memory.

Varnish in Web Hosting

In case you host your sites in a web hosting account with our company, you will be able to add Varnish with a couple of clicks via your Control Panel. The caching platform is offered as an upgrade with all our shared web hosting packages and you can choose the number of the sites that will use it and the total amount of system memory that will be used for the cached content. The two features that can be upgraded in the Control Panel’s Upgrades section are the number of instances and the amount of memory and they aren’t directly tied to each other, so you can decide whether you need lots of memory for a single large-sized site or less memory for multiple smaller ones. You can make use of the full potential of the Varnish caching platform if the websites use a dedicated IP. With the hosting Control Panel, you can swiftly start/restart/deactivate an instance, delete the cached contents independently for each website that uses the Varnish platform or view an elaborate log.

Varnish in Semi-dedicated Hosting

All our Linux semi-dedicated packages include Varnish by default, so you can use the website accelerator and enhance the loading speed of any website that you host on our semi-dedicated servers. You will get 64 MB of memory dedicated to the Varnish accelerator at no additional cost and you can activate an instance with no more than a few mouse clicks through the Hepsia hosting Control Panel, which comes with the semi-dedicated server plans. If you need more memory, the latter is offered in increments of 32 MB through the Upgrades section of the Control Panel and it will be at your disposal straight away. You can also add more instances as an upgrade, so you can decide whether lots of data will be cached for a single site or whether the memory will be utilized by different Internet sites. The Hepsia Control Panel will permit you to reboot or to shut down any instance, to see the system log for it or to delete the cached files using one-click controls. To get the most out of the Varnish accelerator, you can get a dedicated IP address for the websites that will employ it.

Varnish in Dedicated Servers Hosting

If you want the most powerful hosting solution and you obtain any of the Linux dedicated servers hosting packages offered by our company, you’ll be able to use the Varnish content caching platform to optimize the performance of your sites at no additional cost as long as the server is ordered with our next-gen Hepsia Control Panel. Its easy-to-work-with graphical interface will permit you to monitor system processes, to delete the cached content or to restart any instance with one single click. The smallest amount of memory that the Varnish caching platform can use to cache website content is 3 GB, which is quite enough for a large collection of resource-requiring Internet sites, so your dedicated server will be able to deal with a gigantic system load while your visitors are enjoying a smooth web browsing experience. As your dedicated machine will include several different dedicated IP addresses, you’ll be able to make use of Varnish’s full capacity.
